Eine nicht behandelte Ausnahme ist aufgetreten während der Ausführung der aktuellen Webanforderung, "Не найден указанный модуль"
Dass ich auf das MVC-tutorial von Rick Anderson , hier , Seite 4 , nach Hinzugefügt, das Modell und die Datenbank . Jedoch , wenn ich versuche zu gehen, um die URL :
http://localhost:2815/Movies/Index
Bekomme ich diese :
Und so :
Server Error in '/' Application.

Aber das ist seltsam, da die MoviesController.cs , ist :
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using MvcMovie.Models;
namespace MvcMovie.Controllers
{
public class MoviesController : Controller
{
private MovieDBContext db = new MovieDBContext();
//GET: /Movies/
public ActionResult Index()
{
return View(db.Movies.ToList());
}
//... more code
}
Und die Methode public ActionResult Index() hat eine Umsetzung des HTML in der Ansicht Bibliothek :
@model IEnumerable<MvcMovie.Models.Movie>
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
<th>
@Html.DisplayNameFor(model => model.Title)
</th>
<th>
@Html.DisplayNameFor(model => model.ReleaseDate)
</th>
<th>
@Html.DisplayNameFor(model => model.Genre)
</th>
<th>
@Html.DisplayNameFor(model => model.Price)
</th>
<th></th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.DisplayFor(modelItem => item.Title)
</td>
<td>
@Html.DisplayFor(modelItem => item.ReleaseDate)
</td>
<td>
@Html.DisplayFor(modelItem => item.Genre)
</td>
<td>
@Html.DisplayFor(modelItem => item.Price)
</td>
<td>
@Html.ActionLink("Edit", "Edit", new { id=item.ID }) |
@Html.ActionLink("Details", "Details", new { id=item.ID }) |
@Html.ActionLink("Delete", "Delete", new { id=item.ID })
</td>
</tr>
}
</table>
Also , was ist der Grund für die Ausnahme ?
- der Fehler wird Ein Netzwerk-oder instanzspezifischen Fehler beim herstellen einer Verbindung zu SQL Server. Der server wurde nicht gefunden oder ist nicht zugänglich. Stellen Sie sicher, dass der Instanzname richtig ist und ob SQL Server Remoteverbindungen zulässt. (Anbieter: SQL Network Interfaces, Fehler: 56 - Nicht in der Lage zu laden SQLUserInstance.dll aus dem angegebenen Speicherort in der Registrierung. Stellen Sie sicher, dass die Lokale Datenbank-Runtime-Funktion von SQL Server Express ordnungsgemäß installiert ist.
- In der
Index
Methode können Sie fügen Sie so etwas wievar test = db.Movies.ToList();
und sagen Sie uns, wenn Sie diese ausführen, hattest
enthält die tatsächlichen Daten ausMovies
Tabelle, oder Sie erhalten die gleiche Ausnahme?
Du musst angemeldet sein, um einen Kommentar abzugeben.
Natürlich kann ich nicht Lesen Sie die Ausnahme Nachricht, aber es sieht aus wie Ihre Sicht erwartet Sie ein Modell des Typs
List<MvcMovie.Models.Movie>
. Mehr als wahrscheinlich Ihre Datenbank-Kontext nicht zurück geben. Es erscheint wieder eine Liste von Entity-Framework-Daten-Objekte.Müssten Sie konvertieren Sie Ihre entity-Typ zu Ihrem Modell geben. Sie können entweder verwenden Sie ein tool wie AutoMapper, dies automatisch nach einigen minimal-setup, oder Sie können es manuell tun:
Nicht sicher, ob dies ist Ihre eigentliche problem, aber es könnte sich lohnen, die überprüfung basiert auf einem schnellen Blick auf Ihren code.
